本文實(shí)例講述了php銀聯(lián)網(wǎng)頁(yè)支付實(shí)現(xiàn)方法。分享給大家供大家參考。具體分析如下：
這里介紹的銀聯(lián)WAP支付功能，僅限消費(fèi)功能。

1. PHP代碼如下：

復(fù)制代碼 代碼如下:

2. 配置示例    
復(fù)制代碼 代碼如下:
//銀聯(lián)支付設(shè)置
 'unionpay' => [
     //測(cè)試環(huán)境參數(shù)
     'frontUrl' => 'https://101.231.204.80:5000/gateway/api/frontTransReq.do', //前臺(tái)交易請(qǐng)求地址
     //'singleQueryUrl' => 'https://101.231.204.80:5000/gateway/api/queryTrans.do', //單筆查詢請(qǐng)求地址
     'signCertPath' => __DIR__.'/../keys/unionpay/test/sign/700000000000001_acp.pfx', //簽名證書路徑
     'signCertPwd' => '000000', //簽名證書密碼
     'verifyCertPath' => __DIR__.'/../keys/unionpay/test/verify/verify_sign_acp.cer', //驗(yàn)簽證書路徑
     'merId' => 'xxxxxxx',
     //正式環(huán)境參數(shù)
     //'frontUrl' => 'https://101.231.204.80:5000/gateway/api/frontTransReq.do', //前臺(tái)交易請(qǐng)求地址
     //'singleQueryUrl' => 'https://101.231.204.80:5000/gateway/api/queryTrans.do', //單筆查詢請(qǐng)求地址
     //'signCertPath' => __DIR__.'/../keys/unionpay/test/sign/PM_700000000000001_acp.pfx', //簽名證書路徑
     //'signCertPwd' => '000000', //簽名證書密碼
     //'verifyCertPath' => __DIR__.'/../keys/unionpay/test/verify/verify_sign_acp.cer', //驗(yàn)簽證書路徑
     //'merId' => 'xxxxxxxxx', //商戶代碼
 ],

3. 支付示例    
復(fù)制代碼 代碼如下:
$unionPay = new UnionPay();
$unionPay->config = Yii::$app->params['unionpay'];//上面的配置
$unionPay->params = [
    'version' => '5.0.0', //版本號(hào)
    'encoding' => 'UTF-8', //編碼方式
    'certId' => $unionPay->getSignCertId(), //證書ID
    'signature' => '', //簽名
    'signMethod' => '01', //簽名方式
    'txnType' => '01', //交易類型
    'txnSubType' => '01', //交易子類
    'bizType' => '000201', //產(chǎn)品類型
    'channelType' => '08',//渠道類型
    'frontUrl' => Url::toRoute(['payment/unionpayreturn'], true), //前臺(tái)通知地址
    'backUrl' => Url::toRoute(['payment/unionpaynotify'], true), //后臺(tái)通知地址
    //'frontFailUrl' => Url::toRoute(['payment/unionpayfail'], true), //失敗交易前臺(tái)跳轉(zhuǎn)地址
    'accessType' => '0', //接入類型
    'merId' => Yii::$app->params['unionpay']['merId'], //商戶代碼
    'orderId' => $orderNo, //商戶訂單號(hào)
    'txnTime' => date('YmdHis'), //訂單發(fā)送時(shí)間
    'txnAmt' => $sum * 100, //交易金額，單位分
    'currencyCode' => '156', //交易幣種
];
$html = $unionPay->createPostForm();

4. 異步通知示例
復(fù)制代碼 代碼如下:
$unionPay = new UnionPay();
$unionPay->config = Yii::$app->params['unionpay'];
$unionPay->params = Yii::$app->request->post(); //銀聯(lián)提交的參數(shù)
if(empty($unionPay->params)) {
    return 'fail!';
}
if($unionPay->verifySign() && $unionPay->params['respCode'] == '00') {
    //.......
}

希望本文所述對(duì)大家的php程序設(shè)計(jì)有所幫助。
